Python 如何解决Jupyter笔记本中的内核错误？（win64）

我对Jupyter笔记本有点陌生。我在笔记本（Python3）的右上角看到一个内核错误，我也不能运行任何代码

这就是错误：

    Traceback (most recent call last):

请通过创建新的conda环境进行尝试。使用以下命令创建conda环境：

conda create -n <env_name> -c intel python=3.6

source activate <env_name>

conda create-n-c英特尔python=3.6

使用以下命令激活环境：

conda create -n <env_name> -c intel python=3.6

source activate <env_name>

源代码激活

请在此环境中安装所需的软件包。请使用以下命令安装ipykernal：

conda install ipykernel
ipython kernel install --name <env_name> --user

conda安装ipykernel
ipython内核安装--名称--用户

从jupyter笔记本中选择已安装的ipykernal。希望这有帮助

请参阅以下链接，

看起来您遇到了此问题：。如果是这样，修复方法是升级

jupyter_core

包。假设它是随conda安装的，您可以通过打开一个Anaconda命令提示符并运行

conda update jupyter_core

。请向您的提供商寻求有关产品的帮助。这个论坛是关于编程的，你已经将一个与该语言无关的问题标记为

C

。如果我卸载anaconda并再次尝试安装它，它会解决问题吗？
